Design and fabrication of a holey fiber microfluidic device with transverse micro-channel

Abstract

In this report, we present a design of holey fiber structure with six air holes in the cladding and a transverse microfluidic channel intersecting the silica core for liquid detection purpose. The simulation results suggest an improved refractive index sensitivity of the proposed structure compared to that of a single mode fiber with similar transverse channel. The proposed holey fiber structures are fabricated and characterized. Full Text: PDF References J.C. Knight, J. Arriaga, T.A. Birks, A. Ortigosa-Blanch, W.J. Wadsworth and P.St.J.
